Data Structures & Algorithms

This repository contains submissions for tasks from our weekly Data Structures & Algorithms class.

Submissions

To add a submission of a task to the repository, take the following steps.

• Navigate to the website directory from the root of the repository. This can be leetcode, codility or hackerrank
• Find the folder that corresponds to the name of the question.
• Make your submission inside that folder. The name of your file containing your submission should be your name, separated by hyphens. E.g. john-doe

To make your submissions easier to understand by people that want to check it, it would be helpful to add comments explaining it. You should also add indicate the time and space complexities of your submissions.
